SCOPE OF WORK Sec 1.00 Spray injection repairs to Asphalt or Concrete. Repairs to interstates, highways, county,

and township roads including parks and parking lots

Sec 1.01 Description

The work consists of preparing surface by cleaning repair area using high volume air flow, then applying a coating of asphalt emulsion to waterproof and seal surface. Next, a mixture of crushed washed limestone and a binder consisting of liquid emulsion is applied until the patch is brought up to grade. Finally a light coating of dry aggregate is spread over the repair.

Sec 1.02 Materials

Binder: Contractor shall furnish water based liquid emulsion. See attached information Aggregate: Contractor shall furnish crushed washed limestone meeting the proper gradation applicable to the repairs being performed. Commonly used aggregate sizes are the following: Ohio #9 Stone (Sieve Size 1.77 mm) Ohio #8 Stone (Sieve Size 2.36 mm) Ohio #57 Stone (Sieve Size 3.00 mm) Top Cover: Contractor shall apply an application of limestone to the top of the repairs.

Sec 1.03 Equipment: Repairs shall be applied by a Dura Patcher spray injection road repair

machine. Unit shall be capable of applying tack coat, a mixture of aggregate and emulsion binder, plus the ability to apply just stone.

Sec 1.04 Weather limitations: Placement of repair materials should not to be applied before rain

showers. For best result application should be at temperatures above 40 degrees with the exception of emergency situations.

Sec 1.05 Surface Preparation: Clean area to be repaired with high volume air stream

Sec 1.06 Repair Application:

Large Surface Repairs: Apply thin coating of emulsion to the area, then apply a mixture of aggregate and emulsion, once at grade and level, apply a light coating of top gravel to repair area.

Cracks: Apply Emulsion with Vee Jet Nozzle into cracks and thin membrane the length of crack with a minimum of 2” each side from the centerline of the crack. Top coat with #9 aggregate. Severe Cracks with a depth over 2” and width exceeding 1”: Apply mixture into crack, lute excess product to level grade Once repair is at grade and level, a light coating of stone is applied. The repair is then rolled laterally and longitudinally Residential Areas: Compaction with a smooth drum roller may be desired. Sweeping of loose stone is also an option.

Sec 1.07 Method of Measurement: Repairs to be invoiced on a per gallon basis

Sec 1.08 Usage Guidelines:

One gallon of product produces approximately: 10 square feet @ 1” deep repair 20 square feet @ ½” deep repair 40 square feet @ ¼” deep repair

(1) Load is approximately 200 gallons of emulsion and 7 tons of aggregate, this produces around 8 tons of finished product. One load will produce about 4000 square feet @ 1/2" deep of repair area.
